The real reason to use Steelix is to set up Stealth Rock, so I suggest you replace Stealth Rock with either Toxic or Roar.

Toxic is for putting a timer for a switch-in.

Roar is also good for doing a chip damage when paired with Stealth Rock.

You may also try Volt Switch on Zapdos in order to switch in the paper-thin offensive pokemon, such as Infernape and Weavile.
